Question / Help Pixelated stream

[Deleted member 121471]

Greetings

After streaming "Outlast" today, I noticed my stream quality is more pixelated/blocky than I expected when looking at walls, doors and other places, which I didn't expect from 720p@30FPS@3200Kbps and in low motion scenes.

Link to VOD: https://www.twitch.tv/videos/334129347

Is there any setting I can change or add to improve the quality without increasing the bitrate over 3500Kbps or is this really what I can expect at best?

EDIT: Sharpen filter on capture source was turned off for the entirety of the stream.

The advantage of the hardware encoders like NVENC and AMF is removing load off the CPU and putting that load on dedicated hardware on the GPU that is expressly for that purpose.

The tradeoff is significantly reduced quality at low bitrates, to the point that many people suggest using it only for high bitrate encoding best suited for recording rather than streaming.

Myself I don't use hardware encoding under 6000Kbps, and if I can, I use 10000, and even at those bitrates, NVENC produces noticeable pixellation during fast movement.

I'm using x264 to encode my stream. This is why I'm highly confused at why this particular game looks so blocky on most surfaces and wasn't sure if it was wrong settings or if I'm just using too low bitrate for 720p@30FPS@Fast preset.

From a quick look into the VOD, i guess the grain/noise effect in this game is eating up the bitrate.

That didn't even cross my mind, that makes sense. Oh well, going to have to live with it, there's no way to disable it ingame :(
